Method for protecting heat sensitive substrates from fire and excessive heat. |
摘要 |
<p>A method for protecting heat sensitive substrates from fire and excessive heat involves: I. applying to the substrate a layer of a char forming intumescent curable composition comprising: (a) an epoxide group containing material, at least 20 weight percent of said material having an oxirane functionality greater than 2; (b) a curing agent adapted to cure the epoxide group containing material; (c) an additive component comprising a mixture of materials adapted to provide a source of: (i) phosphorous, (ii) zinc, (iii) boron and (iv) an expansion gas upon thermal decomposition, said curable composition being capable of forming a carbonaceous char upon exposure to heat or flame; II. allowing the intumescent curable composition to at least partially cure. r</p> |
